What is Amine and Starch in Iron Ore Flotation about?

This document summarizes a study on the effect of amine and starch dosages on reverse cationic flotation of an iron ore. The study found that: 1) The interaction between amine collector and starch depressant molecules can form a "clathrate" where amine molecules occupy empty spaces in the starch structure, resulting in depression of hydrophobic minerals. 2) At higher amine dosages, this clathrate formation between amine and starch could explain the increased SiO2 content in concentrates from the coarse p
